It was extremely convenient to have my macro's set to any place on the action bar. I think they try to emulate that with the controller, where you hold R2/L2 (or equivalent) and choose away, but unlike WoW those macros don't transfer computers, which I assumed it would and completely wiped a moogle fight because I didn't have em to direct the group :P

It's a small issue in comparison to what SE need to work on, but it will add a little more icing to the cake that's pending completion
